Disposable email address: free, instant and no sign-up
A disposable email address is a throwaway inbox you can use once and forget. TempMailHub creates one the moment you open the page.
How a disposable email address works
Instead of giving a website your real address, you give it a temporary one. Any email the site sends lands in an inbox you can read in your browser. When you no longer need it, you simply stop using it and the messages are cleared automatically.
Why people use them
- To avoid marketing emails after a free trial or download
- To keep a real inbox out of data breaches and mailing lists
- To test sign-up flows and email templates quickly
- To register on sites you only plan to visit once
What you get with TempMailHub
- An address ready as soon as the page loads
- Fast delivery of confirmation links and one-time codes
- Messages removed automatically after up to 30 days
- Gmail-style dot and plus variations with the temp Gmail address page
- Up to 50 addresses at once with the bulk generator after sign-in
Disposable email versus an alias
An alias forwards mail to your real inbox, so your real address is still involved. A disposable address is separate from it. Our comparison of temp mail and Gmail aliases explains when each one makes sense, and what an email alias is covers the basics.
Tips for better results
- Copy the address exactly as shown, with no spaces
- Keep the inbox tab open until the message arrives
- If a site rejects the domain, try a Gmail-style address instead
- Never use a disposable address for accounts you must recover later
When to use a disposable email address
- A site asks for an email only to send one verification code.
- You want a download, a coupon or a trial without joining a mailing list.
- You are testing a sign-up form and need several fresh addresses.

How a disposable address works
- A service creates a random address and an inbox that you can open without a password.
- You paste the address into a sign-up form.
- The site sends a code or link, and the message appears in the inbox.
- Later the messages are deleted. On TempMailHub that happens after up to 30 days.
How long do disposable addresses last?
It varies by service. Some inboxes disappear after minutes, others after hours or days, and time limits change, so check each service's own page. See 20 and 30 minute mail and the 15 minute mail page for how timers affect you.
Risks to know about
- No recovery. If the inbox is gone, you cannot reset the password for that account.
- Public inboxes. On some services anyone who knows the address can read the mail.
- Blocked domains. Some sites refuse known disposable domains.
